DETAILED DESCRIPTION OF THE INVENTION

The technical characteristics, features and advantages of the presentinvention will become apparent in the following detailed description ofthe preferred embodiments with reference to the accompanying drawings.The drawings are provided for reference and illustration only, but notintended for limiting the present invention.

With reference to FIGS. 1 to 3 for a perspective view, a planar explodedview and a planar view of a structure of the present inventionrespectively, the present invention provides an elastic golf club andits club head, wherein the golf club comprises a club head 1, and a rod2 extended from the top of a side of the club head 1, and the club head1 further comprises a club head body 10, an elastic structure 11, and astriking plate 12. With the elastic structure 11 installed between theclub head body 10 and the striking plate 12, the elastic structure 11produces a deformation when the striking plate 12 hits a golf ball 3, soas to provide an elastic force to assist striking the golf ball 3 (asshown in FIG. 4 or 5).

The club head body 10 is hollow, and has two distal openingsinterconnected with each other, a joint opening 100 formed at an end ofthe club head body 10, and an open mouth 101 formed at another end ofthe club head body 10 and disposed at a position corresponding to thejoint opening 100, wherein the joint opening 100 is provided forcoupling the elastic structure 11, and the open mouth 101 is providedfor interconnecting the interior of the club head body 10 with theoutside, such that when the elastic structure 11 is hit or compressed,air inside the elastic structure 11 is discharged to the outside toavoid a resistance produced by a pressure difference.

The elastic structure 11 is a hollow circular body and includes anelastic structure, a plurality of ditches 110 extended axially andarranged with an interval apart from each other on a circularsurrounding surface of the elastic structure for facilitating theformation of a plurality of elastic ribs 111 on the circular surroundingsurface of the elastic structure 11, and each elastic rib 11 is extendedoutwardly into a curved shape, so that the elastic structure 11 can bedeformed and compressed easily when the elastic structure 11 is hit.With a greater deformation, a greater elastic force can be released tostrike the golf ball 3 to a farther target position. In addition, acircular neck 112 is disposed at a rear end of the elastic structure 11and sheathed and coupled into the joint opening 100 of the club headbody 10, and an opening 113 is formed at a front end of the elasticstructure 11 and provided for the striking plate 12 to cover onto theopening 113 of the elastic structure 11. The club head body 10 can beintegrally formed with the elastic structure 11 (as shown in FIG. 7), orthe striking plate 12 can be integrally formed at a front end of theelastic structure 11 (as shown in FIG. 8).

By the aforementioned assembly, the elastic golf club and its club headin accordance with the present invention can be achieved.

With reference to FIG. 4, when a golfer swings the club, and thestriking plate 12 hits the golf ball 3, an impact force is exerted ontothe elastic structure 11, such that each elastic rib 111 is deformed bythe impact force, while the surface of the striking plate 12 is alsodeformed by the impact of the golf ball 3. In FIG. 5, the elasticstructure 11 of the present invention includes the ditches 110 andelastic ribs 111, such that each elastic rib 111 is pressed backwardwhen the striking plate 12 is hit, and the formation of each ditch 110provides sufficient space for the deformation of each elastic rib 111.The greater the deformation produced by each elastic rib 111, thegreater is the released elastic force. If each elastic rib 11 releaseselastic force as shown in FIG. 6, the elastic force will push thestriking plate 12, while the striking plate 12 also provides a pushingforce by its deformation to drive the golf ball 3 to a farther targetposition, so as to provide a greater yardage easily.

Since the elastic structure 11 also provides a shock absorbing effect,the elastic structure 11 absorbs vibrations produced by the golfer whostrikes the golf ball, so as to reduce the golfer's uncomfortablefeeling when striking the golf ball.
